title: [A case report on the repair of an anterior mitral leaflet chordal rupture using PTFE suture].
abstract: Surgical repair of ruptured or elongated chordae tendineae of the mitral valve is one of the most complex reconstructive techniques in cardiac surgery. Various surgical procedures have been described to repair chordal abnormalities of the anterior leaflet of the mitral valve. This case report describes a simple repair technique with a double-armed, pledge-supported, expanded polytetrafluorethylene (PTFE) suture. A 48 year-old-man who had mitral regurgitation due to ruptured chordae tendineae of the anterior mitral leaflet underwent successful chordal reconstruction using 3--0 PTFE suture. Mitral regurgitation was completely repaired as shown by left ventriculogram and echo cardiogram more than one year postoperatively. In this experience, this procedure could be used to treat both elongated and ruptured chordae tendineae.
